l citizen of the United States, and a resident of the city of East St. Louis, county of St. Clair, State of Illinois, have invented a new and useful Improvement in Carbureters, of which -the following is a specification. y

This invention relates to carbureters, and more particularly to devices for va orizing and mixing the'- working fluid use in the propulsion of gas and hydrocarbon engines.

Internal combustion or explosion engines are usually started by a mechanical device operatively connected with the main shaft o the engine whereby the operator may rotate the shaft and thereby cause a prim ing charge of the workin fluid to be drawn into the combustion cham er. It frequentlyA hap ens that .several successive actuations of t e mechanical starting device are neces- S81' and' mixture of the working fluid in the priming charge', thereby causing delay in starting 'and a great amount of exertion on the part of the operator. l

,T ie. principal objects of the presentinvention are to secure perfect vaporization and 'thorough mixture of the air and gases;

to'facilitate the primin and 'quick starting' of the engine; to simplify the'construction; to provide for readily applying the carbureter' tothe fuel inlet of.. hydrocarbon engines of any ordinary construction without' material alteration; and to attain certain other advantages hereinafter. incre fully appearing. l

The invention consists in. tlie arts and in the arrangements and combinations of parts hereinafter described. and claimed.

vIn the accompanying drawing forming part 'of this specification and wherein like symbols -refer to like parts wherever they occur, Figure' 1 is a'view partly in vertical section' and partly .in side elevation of a carbureter einbod ing my invention; and Fi 2 is a front e ovation of the same.

is shown in the drawing," the carburetor comprises a hollow shell 1 whose intermediate portion is cylindrical, the end portions,

2 3 being bent or curved laterally. The sliell or casing is preferablyy made in two separate sections or elbows havinor their nieetin end 'rtions right and leiPt hand screw-t rende respectively, to fit a correspondingly screw-threaded coupling ring 4,

owing to the imperfect vaporizationA cured to the end of a pipe 5. The meeting end portions of the ipe and carbureter are provided with latera ears 6 having alining erforatons ,7 to receive suitable securing lts, not shown.

In the end portion 3 of the shell is a diskvalve lor throttle 8 which is mounted on 'a rod 9 swiveled in the shell and having its upper end portion 10 bent laterally to constitute a handle or arm to cooperate with any suitable cont-rolling or manipulating device.

In the intermediate portion of the shell is mounted a spiral strip 11 whose peripheral portion touches the cylindrical inner face of the shell, thereby forming a spiral passageway or mixingchamber 12. The central portion of the spiral 11 is open to permit the passa e therethrough of a longitudinally-mova vle rod 13 on the lower end -o' which is a needle-valve 14. The needle,- valve projects into and normally closes the discharge opening in the end of a nozzle 15 which is fitted in the .bottom of the casir. Connected to the nozzle is a pipe 16 whi may communicate with any suitable source of supply of hydrocarbon.

The upper end portion of the rod 13 extends through a tubular member or guidesleeve 17 which is screw-threaded into a boss 18 on the upper portion of the casing. The sleeve 17 has a 'am nut 19 threaded thereon and adapted to `e tightened against the u per face of the boss 181 so as to lock t e 95 sleeve in vertically adjusted positions. Mounted on the ro 13 above the needlevalve is a circular late or diaphragm 2Q which is adapted to ift the rod when a suci tionis created throu h the carbureter and thereby lift the need e-valve and open the discharge opening in the nozzle. On the rod 13 is a collar 21 which is arranged to co operate with the inner end of the sleeve i17 to limit the u Ward movement of the rod. Preferably, a ight spring 22 is coiled about the rod between4 the collar and sleeveso as to bear a ainst the ends thereof and yieldingly hol the needle-valve seated in the discharge opening of the nozzle; and by adjusting the sleeve 17 vertically the distance way being arranged to dellect the air to the the needle-valve is raisedmay be varied to bottom o said oil receptacle in a whirling y regulate the discharge of the Huid from the motion. I 60 nozzle. i .2. A carbureter coinpr'isinga tubular cas- In the lower end portion 2 of the casin ing'whose end portion is turned laterally is a short s iral 23. This s iral is arrange and having a spiral passageway through its to defiect e incoming air ownwardly in a body portion, said casing having .a recepwhrling motion so that the air will 'act tacle tor oil at the inner end of said spiral upon the bottom side of the diaphra m 2O passageway, and means for supplying oil to v1o to the engine, the ro to partially va orize mingle therewit e atomization and mixture is then completed in the chamber l2 rawn into tie engine in a hi hly combustible or explosive state.

gVhen the carbureter is used in connection with a hydrocarbon engine and itv is desired to supply a. riming charge in startin the needl ing. The amount of oil is :controlled b an' overliow opening 24 in the bottom of the i casing. rlhestarting device is then forcibly: actuated to rotate the engine shaft and therecreate The inrushing air will be e poolof oil then more thoroughly in the spiral mixing chaine ore entering the combustion chainirst directed into By "e arrangement of carbureter shown,

nis icd throughoutall ranges of the throttle and the 'engine may be alittle exertion on the part of the operator and the annoyancefof excessive is obviated.

Obvionsl able.. modi the device admits of considerto be limited to the specific construction and arrangement shown.
